Read MoreWhat is Metapackage in C# Asp.net Core?
A metapackage in ASP.NET Core is a special type of NuGet package that doesn't contain any actual code or DLLs itself, but instead serves as a collection of dependencies on other packages. The most common example is the Microsoft.AspNetCore metapackage, which is automatically included in many ASP.NET Core project templates. When you install a metapackage, it automatically brings in all its dependent packages, providing a convenient way to include multiple related packages with a single reference.

Read MoreHow to handle errors in middleware C# Asp.net Core?
Error handling in ASP.NET Core middleware provides a centralized way to catch and process exceptions that occur during HTTP request processing. By creating custom exception middleware, you can standardize error responses and logging across your entire application. Custom exception middleware intercepts exceptions before they reach the client, allowing you to log errors, format responses consistently, and hide sensitive internal details from users. Creating Custom Exception Middleware First, create a folder named CustomExceptionMiddleware and add a class ExceptionMiddleware.cs inside it. This middleware will handle all unhandled exceptions in your application − using System; using System.Net; using ...

The Length property gives ...
Read MoreHow to get the thread ID from a thread in C#?
A thread is defined as the execution path of a program. Each thread defines a unique flow of control. If your application involves complicated and time-consuming operations, then it is often helpful to set different execution paths or threads, with each thread performing a particular job. Threads are lightweight processes. One common example of use of thread is implementation of concurrent programming by modern operating systems. Use of threads saves wastage of CPU cycle and increase efficiency of an application. In C#, the System.Threading.Thread class is used for working with threads. It allows creating and accessing individual threads ...
